LAMINATED GOHESIVE INTERWOUND FABRIC BAND.

Specification of Letters Patent. Patented May 11, 192() Applicationfiled December 8, 1916, Serial No. 135,802. Renewed October 24, 1919.SeriaLNo. 333,110.

To all whom it may concern:

Be it known that I, LAWRENCE A. SUBERs, a citizen of the United States,and resident of Lakewood, in the county of Cuyahoga and State of Ohio,have invented certain new and .useful Improvements in Laminated CohesiveInterwound Fabric Bands, of which I hereby declare the following to be afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

The objects of the invention are to provide an improved form of fabricband for use in constructing hose or analogous tubing, belting, or forincorporating in the casing or tube of a pneumatic tire, particularly inconstructing tubing to resist comparatively high internal pressure.

The invention comprises an improvement upon Letters Patent No.1,017,271, granted February 13th, 1912, for a lammated-cohesive-interwound fabric band, and Letters Patent No. 1,136,292, grantedApril 20th, 1915, for reinforced laminated-cohesiveinterwound fabricband.

In the above referred to invention a fabric is formed first as a tubeand then flattened into a band having selvage edges, and the band iscomposed of a predetermined number, of parallel spaced'yarn elements,laid in groups or series in parallel spaced rows, at a predeterminedangle, the rows of one series being crossed by the rows of the otherseries, said series being laid alternately in opposite directions, theseries of each outer lamination filling the spaces between parallellaminations of the inner series, so that when the laminations areflattened together, all interstices are filled, and the sides of thetube each comprise one complete layer. The flattened tubular bands thusconstructed are afterward wound or laid to construct an adjustablelaminated-cohesive-interwound' fabric therefrom, by means of a machineand substantially as described with modifications 1n the prior PatentsNos. 1,052,915, granted April 30, 1912; 1,132,639 granted March 23,1915; No. 1,052,014 granted March 26, 1912; No. 1,152,63 1 granted March23, 1915; 1,052,040, granted April 23, 1912, and others.

In the former applications for Letters Patent a flattened tubular bandhas been described, the walls of which were composed of one completelayer of laminated,

cohering, interwound fibrous yarn elements, with or without a centralband or strip of adhesive elastic material or a central reinforcingstrip.

This fiattened band was produced by means of a machine having a group offour reels alternately rotating in opposite directions about a centralmandrel upon which the bands are formed, in the manner above described.

"The present invention comprises a tubular band constructed of two ormore layers in which each layer has a predetermined number and strengthof yarns or threads and which are laid in laminations at a predeterminedangle, and the second or any succeeding layer may have either such anumber of yarns in each parallel row or group, so as to cover the entiresurface of the first laminated band or can have a predetermined numberof yarns laid at a predetermined angle, that will only cover a portionof the surface of such constructed band which will thenhave apredetermined tensile strength and extensibility according to the numberof layers, the number and strength of the yarns comprising such layers,and the angle of laminations as may be desired for any given strengthand extensibility in the construction of products desired to bemanufactured therefrom.

This band is formed progressively by means of a suitable centralmandrel, a forming machine consisting of two or more groups of reels,each group of reels being such as shown in Patent No. 1,201,774, grantedOctober 17th, 1916, and various other patents.

The first group of reels forms onecomplete layer of fabric, consisting,of four series of spaced parallel rows of fibrous .yarn elements, eachelement comprising a predetermined number of yarns, and each seriescrossing adjacent series at a predetermined angle upon a suitablecentral mandrel and the second group of reels form a second layer formedin a manner similar to the first group of reels with the exception thatthe series composing the second or any succeeding layer may be laminatedat different angles in the different layers and each parallel row offibrous yarn elements in the series of the second or any succeedinglayer may have such a predetermined number of yarns that it will onlycover a portion of the surface of the band.

creased predetermined tensile strength and -predetermined extensibility.The tube thus formed is coated with an elastic adhesive and coheringsubstance and is thereafter collapsed into a flat flexible band which-isfinally compressed and dried.

The improved band is illustrated in the accompanying drawing. Figure 1is a plan view of the preferred form of my invention comprising outerand inner layers, a central or axial band, and additional bandsintermediate of the layers; Fig. 2is an edge view of the same; Fig. 3 isan enlarged transverse section thereof.

In these views A represents a central or axial strip to which thefibrous yarn elements adhere. This central strip may consist of elasticcohering material or fabric coated with such elastic cohering materialand preferably vulcanizable which will readily adhere to the coatedfibrous yarn elements. B. B. represents the spaced fibrous yarn elementspreferably formed of fine cotton threads embedded in preferablyvulcanizable and elastic cohering material. Said fibrous yarn elementscan be made of long or short staple cotton and be employed in theproduction of the band with good effect. C. C. are the spaced fibrousyarn elements laid or wound upon and crossing the elements B. B. at apredetermined angle and forming the second series or lamination. D. D.are the spaced fibrous yarn elements forming the third series orlaminations and are arallel with the first wound elements B. The bandsin the third lamination register with the spaces between said firstwound elements. E. E. are the spaced fibrous yarn elements comprisingthe last lamination of the first layer, and are laid or wound parallelwith the elements 0. C. These four series or lamination complete thefirst layer.

In the second layer F, F, are the parallel spaced fibrous yarn elementsof the first series or lamination lai d or wound at a predeterminedangle, G, G arethe'fibrous yarn elements of the second series orlamination crossin the first lamination F of the second ,layer, H arethe fibrous yarn elements forming the third series or lamination of thesecond layer and are laid or wound parallel with each other and into thespaces left by the elements F, F. The fibrous yarn coated with suchelastic cohering substance are interposed on between the layers L and Lboth sides of the band after the first group of reels have completedtheir laminations for the purpose of increasing the thickness andflexibility of the band, and

additional bands or strips can be similarly inclosed between the layersat the edges at N. N. if desired.

It is obvious that, in constructing a band similar tothe one describedin my invention, more than two layers of fibrous yarn elements may beemployed, and the angle at which the second or any succeeding layer isapplied need not be laid at the same angle as the first layer, and it isfurther obvious that in coating the fibrous elements with an elasticcohering and adhesive substance that either vulcanizable compounds suchas rulr ber or other adhesive compounds may be applied which will givethe desired result, without departing from the spirit of my invention orscope of my claim.

Having, described the invention what I claim as new and desire Patent isA fabric band including a central axial band shaped core in whichvulcanizable material is incorporated, a layer thereon inclosing thesame formed of laminated spaced parallel series of fibrous bandscohering in a vulcanizable material, and an outer layer of laminatedcohering spaced parallel bands superimposed upon the first named series,and a flattened member in which vulcanizable material is incorporated,inter,- posed between said outer and inner layers.

In testimony whereof, I hereunto set my hand-this 17th day of November,1916.
